- manipulate the state of the keyboard, or display the type of the keyboard, or change the default keyboard abort sequence effect
kbd [-r] [-t ] [-l] [-a enable | disable | alternate]
[-c on | off] [-d keyboard device]
[-D autorepeat delay] [-R autorepeat rate]kbd [-i] [-d keyboard device]
kbd -s [language]
kbd -b [keyboard | console] frequency
The kbd utility manipulates the state of the keyboard, or displays the keyboard type, or allows the default keyboard abort sequence effect to be changed. The abort sequence also applies to serial console devices. The kbd utility sets the /dev/kbd default keyboard device.
The -i option reads and processes default values for the keyclick and keyboard abort settings from the keyboard configuration service, svc:/system/keymap:default. Only keyboards that support a clicker respond to the -c option. To turn clicking on by default, add or change the value of the keymap/keyclick property in the keymap service to:
$ svccfg -s keymap:default setprop keymap/keyclick=true $ svcadm refresh keymap
Next, run the command kbd -i to change the setting. Valid settings for the keymap/keyclick property are true or false. All other values are ignored. If the keymap/keyclick property is not specified in the keymap service, the setting is unchanged.
The keyboard abort sequence effect can only be changed by a super user using the -a option. This sequence is typically Stop-A or L1-A and Shift-Pause on the keyboard on SPARC systems, F1-A and Shift-Pause on x86 systems, and BREAK on the serial console input device on most systems.
A BREAK condition that originates from an erroneous electrical signal cannot be distinguished from one deliberately sent by remote DCE. As a remedy, use the -a option with Alternate Break to switch break interpretation. Due to the risk of incorrect sequence interpretation, binary protocols such as SLIP and others should not be run over the serial console port when Alternate Break sequence is in effect.
Although PPP is a binary protocol, it has the ability to avoid using characters that interfere with serial operation. The default alternate break sequence is CTRL-m ~ CTRL-b, or 0D 7E 02 in hexidecimal. In PPP, this can be avoided by setting either 0x00000004 or 0x00002000 in the ACCM. This forces an escape for the CTRL-b or CTRL-m characters, respectively.
To do this in Solaris PPP 4.0, add:
asyncmap 0x00002000
to the /etc/ppp/options file or any of the other configuration files used for the connection. See pppd(1M).
SLIP has no comparable capability, and must not be used if the Alternate Break sequence is in use.
The Alternate Break sequence has no effect on the keyboard abort. For more information on the Alternate Break sequence, see zs(7D),se(7D), and asy(7D).
On many systems, the default effect of the keyboard abort sequence is to suspend the operating system and enter the debugger or the monitor. Some systems feature key switches with a secure position. On these systems, setting the key switch to the secure position overrides any software default set with this command.
To permanently change the software default effect of the keyboard abort sequence, first add or change the value of the keymap/keyboard_abort property in the keymap service to:
$ svccfg -s keymap:default setprop keymap/keyboard_abort=disable $ svcadm refresh keymap
Next, run the command kbd -i to change the setting. Valid settings are enable, disable, and alternate; all other values are ignored. If the variable is not specified in the keymap service, the setting is unchanged.
To set the abort sequence to the hardware BREAK, set the value of keymap/keyboard_abort in the keymap service to:
$ svccfg -s keymap:default setprop keymap/keyboard_abort=enable $ svcadm refresh keymap
To change the current setting, run the command kbd -i. To set the abort sequence to the Alternate Break character sequence, first set the current value of the keyboard_abort property in the keymap service to:
$ svccfg -s keymap:default setprop keymap/keyboard_abort=alternate $ svcadm refresh keymap
Next, run the command kbd -i to change the setting. When the Alternate Break sequence is in effect, only serial console devices are affected.
To set the autorepeat delay by default, set the repeat_delay property in the keymap service to the expected value with units in milliseconds (ms). To avoid making the keyboard unusable due to a typographical error, delay values below KIOCRPTDELAY_MIN (defined in /usr/include/sys/kbio.h) are rejected with EINVAL:
$ svccfg -s keymap:default setprop keymap/repeate_delay=500 $ svcadm refresh keymap
To set the autorepeat rate by default, set the repeat_rate property in the keymap service to the expected value with units in milliseconds. Negative and zero repeat rates are ejected with EINVAL:
$ svccfg -s keymap:default setprop keymap/repeate_rate=40 $ svcadm refresh keymap
To change the current settings of delay and rate, run the command, kbd -i. When the Auto Repeat Delay and/or Auto Repeat Rate are in effect, only command line mode is affected.
To set the language by default, set the keymap/layout property in the keymap service to the expected language. These languages supported in kernel can be found by running kbd -s. Other values are ignored. For example, the following sets Spanish layout to the keyboard:
$ svccfg -s keymap:default setprop keymap/layout=Spanish $ svcadm refresh keymap
Next, run the kbd -i to change the setting. When Solaris reboots, the Spanish key table is loaded into kernel. These layouts are valid for usb and ps/2 keyboards.
To set the keyboard beeper frequency by default, set the keymap/kbd_beeper_freq property in the keymap service to the expected value with units in HZ. This value should be between 0 and 32767, inclusive. Otherwise it is rejected with EINVAL:
$ svccfg -s keymap:default setprop keymap/kbd_beeper_freq=2000 $ svcadm refresh keymap
To set the console beeper frequency by default, set the keymap/console_beeper_freq property in the keymap service to the expected value with units in HZ. This value should be between 0 and 32767, inclusive. Otherwise it is rejected with EINVAL:
$ svccfg -s keymap:default setprop keymap/console_beeper_freq=900 $ svcadm refresh keymap
To change the current settings of the keyboard beeper frequency and console beeper frequency, run kbd -i.
The following options are supported:
Enables, disables, or alternates the keyboard abort sequence effect. By default, a keyboard abort sequence suspends the operating system on most systems. This sequence is typically Stop-A or L1-A and Shift-Pause on the keyboard on SPARC systems, F1-A and Shift-Pause on x86 systems, and BREAK on the serial console device.
The default keyboard behavior can be changed using this option. The -a option can only be used by a super user.
Enables the default effect of the keyboard abort sequence (suspend the operating system and enter the debugger or the monitor).
Disables the default/alternate effect and ignores keyboard abort sequences.
Enables the alternate effect of the keyboard abort sequences (suspend the operating system and enter the debugger or the monitor) upon receiving the Alternate Break character sequence on the console. The Alternate Break sequence is defined by the drivers zs(7D), se(7D), asy(7D). Due to a risk of incorrect sequence interpretation, binary protocols cannot be run over the serial console port when this value is used.
Sets the beeper frequency for keyboard or console.
Set the keyboard beeper frequency to the operand in HZ. See OPERANDS.
Sets the console beeper frequency to the operand in HZ. See OPERANDS.
Turns the clicking of the keyboard on or off.
Enables clicking
Disables clicking
Specifies the keyboard device being set. The default setting is /dev/kbd.
Sets the autorepeat delay in milliseconds.
Sets keyboard properties from the keymap service. With the exception of -d keyboard device, this option cannot be used with any other option. The -i option instructs the keyboard command to read and process keyclick and keyboard abort default values from the keyboard properties in the keymap service. The -i option can only be used by a user or role with the Device Security Rights Profile.
Returns the layout code of the keyboard being used, and the autorepeat delay and autorepeat rate being used.
If used with -R or -D option, this option returns the value before the changes.
Resets the keyboard as if power-up.
Sets the autorepeat rate in milliseconds.
Sets the keyboard layout into kernel.
If language is specified, the layout is set to language. If language is not specified, a list of available layouts are presented, prompting for the user to specify the language. See OPERANDS.
Returns the type of the keyboard being used.
The following operands are supported:
The frequency value specified to be set in kernel. The receiver of this value is specified by the -b option. This value should be between 0 and 32767 otherwise it is ejected with EINVAL.
The language specified to be set in kernel. If the language is not found, the languages supported are listed for selection. It only applies to -s option.

kmdb(1), loadkeys(1), svcs(1), inetd(1M), inetadm(1M), svcadm(1M), pppd(1M), keytables(4), attributes(5), smf(5), kb(7M), zs(7D), se(7D), asy(7D), virtualkm(7D)
Some server systems have key switches with a secure key position that can be read by system software. This key position overrides the normal default of the keyboard abort sequence effect and changes the default so the effect is disabled. When the key switch is in the secure position on these systems, the keyboard abort sequence effect cannot be overridden by the software default, which is settable with the kbd utility.
Currently, there is no way to determine the state of the keyboard click setting.
The kdb service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/keymap:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibility for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view configuration information for this service. The service's status can be queried using the svcs(1) command.
